Question

Process of silage preparation

Answer 1

Making Silage: The Fermentation Process

Six Phases of the Ensiling Process.

PHASE 1 Aerobic microorganisms are present on the forage surface at the time of harvesting. ...

PHASE 3 This is a transition phase in which the lower pH favours the growth of an anaerobic group of bacteria that produce lactic acid, replacing those that produce acetic acid.

Answer 2

Answer:

1. Plan ahead. You will need to know when the right time to start silaging so that you get the crop cut at the right stage for the best feed quality possible.
2. Assess the crop. For most cereal crops, the best time to cut is when they are at the soft-dough stage. The majority of the plant should still be green, but with a bit of yellowish tinge, especially on the heads of the plant.
3. Cut the crop into swaths. Unlike with making haylage, the best machine to use to cut a crop with is a swather, not a hay mower.
4. Allow the swaths to wilt down for about half a day before harvesting. The forage will need to be dried down to about 60 to 70% moisture before chopping for silage.
5. Harvest the crop. Machines called "forage harvesters" like the one in the photo above (which is a "self-propelled" harvester) are used to chop up the swathed forage and feed it out through a long, tall spout that can literally "spit" out the feed at quite a distance.
6. Pack the silage well. The silage pile must be packed very well, and should be packed down during and after each harvesting day
7. Cover the pile immediately. Use the proper plastic recommended for covering silage. Often recommended and used is polyethylene plastic that may be black on both sides or white on one side and black on the other. The cheaper stuff is all black, but the better quality is the black and white plastic.
8. Weigh the plastic down well. Use numerous old or recycled tires all over the top part of the pile. Hay bales can also be used to hold down plastic on the sides if the silage pile is not in a bunker.
9. Repair any holes immediately. Holes in the plastic can cause massive spoilage problems over time.
